prototypes dropped. 7 December US Army Grumman OV-1B Mohawk, 62-5894, of the 122nd Aviation Company, on photo mission out of Fleigerhorst AAF, Hanau, Germany, is written off after engine failure then fire. Pilot Capt. Bill Ebert and crewman SP4 Ken Bakos eject.

CIA pilot Walter Ray successfully ejects but is killed upon impact with terrain due to failed seat-separation sequence. The Air Force-issue seatbelt failed to release properly. The aircraft had run out of fuel for a variety of reasons. 5 January Martin MGM-13 Mace, launched from Site A-15, Santa Rosa Island, Hurlburt Field, Florida, by the 4751st Air Defense Missile Squadron at ~1021 hrs., fails to circle over Gulf of Mexico for test mission with two Eglin AFB McDonnell F-4 Phantom IIs, but heads south for Cuba. Third F-4 overtakes it, fires two test AAMs with limited success, then damages unarmed drone with cannon fire. Mace overflies western tip of Cuba before crashing in Caribbean 100 miles south of the island. International incident narrowly avoided. To forestall the possibility, the United States State Department asks the Swiss Ambassador in Havana to explain the circumstances of the wayward drone to the Cuban government. The Mace had been equipped with an "improved guidance system known as 'ASTRAN' which is considered unjammable." (This was apparently a typo for ATRAN – Automatic Terrain Recognition And Navigation terrain-matching radar navigation.) 7 January U.S. Navy Lockheed P-2 Neptune on training mission with nine Naval Reservists on board, on out-and-back flight from the Naval Air Facility, Andrews AFB, Maryland, crashes in light rainstorm near Upper Marlboro, Maryland, killing all crew.
